Selecting an object from a List

Question

Hi I have a list: public List Cars = new List (); I want to create a method which could select a Car object from the list, and change it's properties. For example I want to rename the mileage. Car.mileage = 1000; How can I change the properties of the a Car inside a List? Thanks

hello, Add a property in the Car class. Here is a brief example. public class Car { public Car() { // // TODO: Add constructor logic here // } public string Name{get ; set;} public string Brand { get; set; } public string Plate { get; set; } public int Mileage { get; set; } } Test car internal List CreateDummyCars() { List myCars = new List (); myCars.Add(new Car { Brand = "Toyota", Mileage = 10, Name = "Toyota", Plate = "P1234" }); myCars.Add(new Car { Brand = "BMW", Mileage = 500, Name = "BMW", Plate = "BMW1" }); myCars.Add(new Car { Brand = "Honda", Mileage = 10000, Name = "Honda", Plate = "112233" }); myCars.Add(new Car { Brand = "Kia", Mileage = 5678, Name = "Kia", Plate = "Kia123" }); return myCars; } protected void Page_Load(object sender, EventArgs e) { List cars = CreateDummyCars(); foreach (Car c in cars) { if (c.Plate == "BMW1") //let say we want to change the mileage for the car with the plate # BMW1 { c.Mileage = 1000; } } }
